Should it be desired to fill the boiler beyond the normal level, "as maybe the case after working hours or duringa period of rest, this may bereadily done by turning the vhand-wheel p in the proper direction toun-' seatvalve g. When the required level-is reached, the hand-wheel isturned inwthe opposite direction so as to close the valve, therebyrestoring the apparatus to normal working condition. During the timethat the valve is closed, the water-fed through the main pipe line bythe pump (not shown) is returned torthe latter by way of a by-passconnection of some character which is in-7 cluded in the pipe-line atany suitable point but which, since it forms no part of the invention,requires neither illustration'nor description.

l In the modifiedac onstruction represented -in- Fig. 3, the valve stemf instead of being immediately connected to nut d for actuation thereby,is operated through the intermediary of a link or. lever g", which. ispivoted at one'endiat g to a projectiongor lug on the valve'casingandat, the other "end at gt to an adjustable collar carried by the valvestem, the nut being provided with a screw which is pivoted to thecentralportion of "saidlever, The latter lwilllthus be rocked about thepivot g as a'fulcrum during the expansion and contraction of thethermpstatic tube "b and; in consequence, will lower or raise the valve.Figs. 4 and 5jsl1ow two such levers arranged in toggle fashion,
